:传统的交通灯控制器多数由单片机或PLC来实现,文中介绍了基于VHDL硬件描述语言进行交通灯控制

器设计的一般思路和方法。选择XIL INX公司低功耗、低成本、高性能的FPGA芯片,采用ISE5. X和MODELSIM

SE 6. 0开发工具进行了程序的编译和功能仿真。最后给出了交通灯控制器的部分VHDL源程序和仿真结果,仿

真结果表明该系统的设计方案正确。-Traffic light controller is usually developed bymicro p rocessor or PLC. This paper introduces the gen2

eral design methods of traffic light controller base on VHDL ( hardware descrip tion language). the FPGA chip of XIL2

INX Corporation was chosen with the low power loss, the low cost and the high performance, the XIL INX ISE5. X

andMODELSIM 6. 0 development toolswas used to comp ile and stimulate. Finally, The VHDL source p rogrammer

and simulating results of traffic light controller are given. The simulating results show that the design method is cor2
